Method and apparatus for transceiving data using plurality of carriers in mobile communication system

1. A communication method of a terminal in a mobile communication system, the method comprising:

receiving, from a primary serving cell (PCell), a first control message including secondary serving cell (SCell) configuration information for an SCell and discontinuous reception (DRX) configuration information;

applying, when the first control message includes an indicator indicating that a first base station for the SCell is different from a second base station for the PCell, the DRX configuration information to the SCell of the first base station;

receiving a second control message including a DRX media access layer (MAC) control element (CE);

determining whether the DRX MAC CE is received from a non-primary set serving cell or a primary set serving cell; and

stopping, if the DRX MAC CE is received from the non-primary set serving cell, the DRX timer for the non-primary set serving cell.

2. The method of claim 1 , further comprising applying, if the first control message does not include the indicator, the DRX configuration information to the PCell of the second base station.

3. The method of claim 1 , further comprising stopping, if the DRX MAC CE is received from the primary set serving cell, the DRX timer for the primary set serving cell.

4. The method of claim 1 , wherein the DRX configuration information comprises at least one of an active time timer and a DRX-cycle parameter.

5. A communication method of a primary base station in a mobile communication system, the method comprising:

transmitting, to a terminal, a first control message including secondary serving cell (SCell) configuration information for an SCell to be added and discontinuous reception (DRX) configuration information, the first control message including an indicator indicating that a first base station for the SCell is different from a second base station for the PCell; and

transmitting a second control message including a DRX media access layer (MAC) control element (CE).

6. The method of claim 5 , wherein the DRX configuration information comprises at least one of an active time timer and a DRX-cycle parameter.

7. A communication method of a base station in a mobile communication system, the method comprising:

receiving a secondary serving cell (SCell) add request message from a first base station for a primary serving cell (PCell);

transmitting a SCell parameter and discontinuous reception (DRX) configuration information to the first base station; and

transmitting a control message including a DRX media access layer (MAC) control element (CE),

wherein the DRX configuration information is applied to a SCell of a second base station, if the second base station for the SCell is different from the first base station for the PCell.

8. A terminal comprising:

a transceiver configured to communicate with a base station; and

at least one processor configured to:

control receiving, from a primary serving cell (PCell), a first control message including secondary serving cell (SCell) configuration information for an SCell and discontinuous reception (DRX) configuration information, and

applying, if the first control message includes an indicator indicating that a first base station for the SCell is different from a second base station for the PCell, the DRX configuration information to the SCell of the first base station,

wherein the at least one processor is further configured to control receiving a second control message including a DRX media access layer (MAC) control element (CE), determining whether the DRX MAC CE is received from one of a non-primary set serving cell and a primary set serving cell, and stopping, if the DRX MAC CE is received from the non-primary set serving cell, the DRX timer for the non-primary set serving cell.

9. The terminal of claim 8 , wherein the at least one processor is further configured to control applying, if the control message does not include the indicator, the DRX configuration information to the PCell of the second base station.

10. The terminal of claim 8 , wherein the at least one processor is further configured to control stopping, if the DRX MAC CE is received from the primary set serving cell, the DRX timer for the primary set serving cell.

11. The terminal of claim 8 , wherein the DRX configuration information comprises at least one of an active time timer and a DRX-cycle parameter.

12. A primary base station comprising:

a transceiver configured to communicate with a terminal; and

at least one processor configured to control transmitting, to a terminal, a first control message including secondary serving cell (SCell) configuration information for an SCell and discontinuous reception (DRX) configuration information, the first control message including an indicator indicating that a first base station for the SCell is different from a second base station the PCell,

wherein the controller is further configured to control transmitting a second control message including a DRX media access layer (MAC) control element (CE).

13. The primary base station of claim 12 , wherein the DRX configuration information comprises at least one of an active time timer and a DRX-cycle parameter.

14. A non-primary base station comprising:

a transceiver configured to communicate with a terminal; and

at least one processor configured to:

control receiving a secondary serving cell (SCell) add request message from a first base station for a primary serving cell (PCell), and

control transmitting a SCell parameter and discontinuous reception (DRX) configuration information to the first base station,

wherein the DRX configuration information is applied to a SCell of a second base station, if the second base station for the SCell is different from the first base station for the PCell, and

wherein the at least one processor is further configured to control transmitting a control message including a DRX media access layer (MAC) control element (CE).
